1 Claim. 1

tric lamp bulb, is especially well adapted for use on table and floor lamps.

One of the objects of this invention is to provide an ornamental finial operated mechanism for actuating an electric switch in the socket for an electric lamp bulb.

Another object of this invention is to provide an ornamental finial operated mechanism for reciprocating the push-through switch member in the socket for an electric lamp bulb.

A further object of this invention is to provide an ornamental finial applicable to the frame of a table or floor lamp shade for operating mechanism to actuate the switch in the socket of an electric lamp bulb.

Other objects of this invention will be apparent from the following description and accompanying drawing.

To the above end, generally stated, the invention consists of the novel devices and combination of devices hereinafter described and defined in the claim.

In the accompanying drawing, which illustrates the invention, like characters indicate like parts throughout the several views.

Referring to the drawing:

Fig. 1 is an elevational view of a table lamp having the invention embodied therein, portions of the lamp shade being broken away;

Fig. 2 is a fragmentary view looking at the parts shown in Fig. 1 from the left, with the exception of the lamp shade which is removed; and

Figs. 3 and 4 are views principally in plan, with some parts sectioned on the lines 3-3 and 4-4 of Fig. 1, respectively, on an enlarged scale, and with the lamp bulb removed.

For showing one embodiment of the invention, there is shown in the drawing an electric table lamp indicated as an entirety by the numeral 5 with the exception of its switch socket member 6, a light bulb 1 in said socket member and a shade 8. The switch in the socket 6 includes a push-through member 9 in the form of a cylindrical member having rounded ends. The shade B is mounted on a support I0 secured to the socket member 6. A member ll detachably secures the shade 8 to the support I 0. Integral with the member [I is a pair of upstanding bearing ears l2.

An ornamental finial l3, simulating a bird, has a depending lug l4 that extends between the bearing ears l2 and is secured thereto by a pivot pin l2. Rigidly secured to the initial l3, at the lug I4, is a rearwardly and downwardly inclined stem 15.

A divided clamp 16 is applied around the socket member 6 and has outturned apertured ears I! through which a stove bolt [8 extends and frictionally holds said clamp on the socket member 6. A bell-crank i9 is pivoted to the clamp l6 diametrically opposite its ears H, as indicated at 20. This bell-crank I9 has a depending short arm 2| and a long upright L-shaped arm 22. A pivoted link 23 connects the stem l5, at its outer end, to the upper end of the bell-crank arm 22. The short bell-crank arm 21 is attached to the switch button 9 by a yoke 24 in the form of a horizontally disposed fiat bar turned vertically edgewise. This yoke 24 has, in its end portions, holes 25 into which the rounded ends of the switch member 9 extend part way, see Fig. 4. The yoke 24 is applied to the switch button 9 by a springing action. On the lower end portion of the short bell-crank arm 2| is an outwardly proiecting pivot pin 26 that extends through a hole 21 in the yoke 24 at the longitudinal center thereof.

Obviously, by tilting the finial or bird l3, downwardly, the switch member 9 will be moved into one of its extreme positions and by tilting said bird upwardly, the switch member 9 will be tilted into its other extreme position.

From what has been said, it will be understood that the invention described is capable of modifications as to details of construction and arrangement within the scope of the invention herein disclosed and claimed.

What I claim is:

The combination with an electric lamp having a switch socket provided with a switch operating member of the push-through type, a shade frame supported from the switch socket, a shade supported on said frame, said frame having a member securing the shade at the top thereof, of a finial detachably secured to the last noted member for pivotal movement in a vertical plane and having a stem that extends outwardly and downwardly substantially to the top of the shade, a yoke embracing the switch socket and having at its end portions separable interlocking engagement with the end portions of the switch operating member, a clamp applied to the switch socket above the yoke, a bell-crank pivoted to the clamp, the motions of the switch operating member and the bell crank being in parallel planes, said bell-crank including a short depending arm pivoted to the yoke at its intermediate portion, said bell crank also including a long arm that projects outwardly and then upwardly, and a link pivotally attached to the upper end of the long arm of the bell-crank and the outer end of the finial stem.
